To all whom it may concern: Be it known that I, WILLIAM EDGAR MUNTZ, a subject of the King of Great Britain, and resident of24 Southampton Buildings, London, England, haveinvented new and useful Improvements in Means for: Regulating the Flow of Liquids, of which.

the following'is a'specification.- I

This invention relates to improvements in the regulation of the flow of fluidsi The object of this invention isto provide means whereby a number ofhdifierentvo'humes of a mixture of two fluids can be dis charged, whilst at the'sanie time the pro portion of the two fluids for'each volume is capable of infinite variation. 7

In one way of carrying out my invention as applied to a spigot tap, the'two fluids. in the casing are separated by a diaphragm in the casing situated in a plane at right angles to the axis of rotation or" the spigot plug. In the surface of the casing contiguous to the plugI cut one or more pairs of triangular, rectangular or trapezoidal slots, the longitudinal centre lines of the triangular slots being preferably at right angles to the axis of rotati n. one slot aboveand the other below the diaphragm dividing the two fluids, such triangular slots facing opposite ways.

In the spigot I form along'practically its full length a slot,-prefera'bly oblong,whose longitudinal centre line is preferably parllel to the axis of thespigot. "The base of each casing slot is of such width that when it inter-registers with the slot in the spigot plug a certain predetermined fluid passage results, say 11;, or =1- or allot the fuel supply. The pairs of triangular casingslots i'ace opposite ways and the base of one so far overhangs the apex of the other and vice versa that when the spigot slot registers with the extremity of the'baseof one of the twocasing slots (in that particular sector) to give the predetermined fluid passage above alluded to, the apex-of- 'theother slot does not-impinge and is just clear of the said spigot-slot so as torelease the full quantity of one .fluid (undiluted 'bythe other) for which that particular sector is designed. When applying my invention'to a spigot tap in which tWO'iflUidS lH;;tll6 casing are separated by a diaphragm'inthe casing. a plane parallel to the axis: of rotationjiof the spigot plug I form two slots, in the plug diametrically opposite vto each other, one

slot extending from the topnear to'the iniolthe plug, whilst the other slot extends from the bottom near to the middle of thedle oi plug. In this case the arrangement of the slots. in the casingis similar, each slot in. the plug being adapted to uncover slots governing. the flow I of one fluid during one half-revolution ofthe plug and slots governing the flow ofthe other fluiddub.

. ing the other half revolution of thespigotw From the above it will be'understood that" it as the spigot slot ismoved the volume of the fluid discharge remains practically con-1.

stant until the full volume ofo'ne of the fluids is being discharged, whilst'the proportion of'the two ingredients :is capableof infinite variation.

Whilst the invention as above described is I particularlyuseful forwater taps as used tor certain purposes, it is also useful for.

incandescent gas burners, gasfires and the like, as it gives positive air admission which.

is so desirable, and also enables the, pro

. y, moment "as the pressure and quality of portion of air to gasto be varied at either or bothgas andatmo'spheric airmay,

combined, but also for the-hermetic sealing of the outlets of both fluids.

l y invention is illustrated in the accompanying drawings, in which Figure 1 shows the development or layout of a casing of a spigottap havinga diaphragm in a plane at right angles to the axis of the plug and suitable for regulating the flow of hot and cold water, and Figure 2ishows, a similar layout in which the casinghas-a diaphragm parallel with theaxis of rotation, of the I plug. "Figure Brisaisectional elevation of a tap and Figure 4 is an'end'elevatlon of Figured V For convenience in describing the-invention the casing has been divided by 'dotted' Y lines into equal. partsinumbered 0, 10, 20 etc.. Referring more particularly to Figure 1; A is a diaphragm dividing the 0381119,,C0ldwater, for example b'eingjadmitted to. the

casing above, and hot water below, the 'dia i flow of fluids of different character to thesaid compartments of the housing.

4. A device of the character described comprising, a hollow spigot plug, a easing into which said plug is fitted, said plug having a pair of slots in its wall extending. in a direction substantially parallel to its axis of rotation and throughouta part of its length, said casing being provided with a plurality of pairs of slots extending in a direction substantially at right angles to the axis of rotation of the plug, each of said slots having a base portion equivalent in .area to a predetermined fraction of the area of the slot in the spigot plug and a substantially triangular portion, the triangular portions of each slot of a pair tapering in opposite directions, means for rotating the spigot plug in the casing for causing the spigot slots and easing slots to intereregister in difi'erent relationships, a housing surrounding said casing with a water-tight fit, opposed webs or diaphragms extending substantially parallel to the axis of rotation of the spigot plug and connecting the casing and housing for dividing the latter into two water tight compartments, and means for permitting the inflow of fluids of difi'erent character to the said compartments of the housing.

5. A device of the character described comprising, a hollow spigot plug, a casing into which said plug is fitted, said plug having a pair of slots in its wall substantially parallel to its axis of rotation, one of said slots lying above andthe other below the horizontal central plane of the plug, said casing being provided with a plurality of pairs of slots extending in a direction subwater-tight compartments, the said triangular portions of the slots in the casing tapering oppositely to each other on each side of the said webs, means 'for permitting the inflow of fluids of different character tothe said compartments of the housing, and 4 casing for causing the slots in the spigot plug to inter-register either simultaneously or individually with the casing slots in different relationships.

' 6. A device of the character described comprising, a hollow spigot plug, a casing into which said plug is fitted, said plug havmeans for rotating the spigot plug in the 7 ing a pair of slots in its wall'substantially stantially at right angles to the axis of rotation of the plug, each of said slots having a substantiallytriangular portion, certain of said slots having a portion equivalent in area to a predetermined fractionof the area:

of the slots in the spigot plug, a housing surrounding said casing with a water-tight fit, opposed webs or diaphragms extending substantially parallel to the axis of rotation i of the spigot plug and connecting the casing and housing for dividing the latter into two water-tight compartments, the said triangular portions of the slots in the casing tapering oppositely to each other on each side of the said webs, means for permittingthe inflow of fluids of dii'lerent'character to the said compartments of the housing, and means for rotating the spigot plug in the casing for causing the slots in the spigot plug to inter-register either simultaneously or individually with the casing slots in different relationships; v

7. In a valve device, a housing, a pair oi inlet ports in the housing for difierent sources of supply, a valve "within the hous ing, a pair of ports in the valve, each port of one pair of ports comprising a full width portion and a tapered portion, and arranged to be so brought into registration with a corresponding port of the other pain of ports, that when the .full width portion or" either port of the said one pair ofport-s is beginning to leave registry with itscorresponding inlet port, the other of the said one pair of ports is beginning to make registry with its corresponding port.

In testimony that I claim the foregoing as my invention I have signed my. name this 11th day ofFebruary, L921.
